This is a printable picatinny flashlight mount for the Sofirn SC31 Pro. It uses a print in place clamping system and only requires 4 m3 screws and nuts (more info in readme)
This does require a dialed in printer, but can be done on ender 3 style no problem.
I cant verify if this light will handle the shock of larger calibers.
This might fit other Sofirn 18650 flashlights that use the same battery tube. It fits one of my right angle lights...
